It weems to me, if we're going to get upset over the use of undecagon and duodecagon because they are not 'proper', we not to also do away with triangle and quadrilateral and stick to trigon and tetragon. After all if it's important for 11- and 12- sided figures, it should be important for 3- and 4- sided figures. We should strive for consistency when it's needed.
